Don't fail CI on failing Windows 32-bit

[MilesCranmer]

This changes the main test suite to not fail the entire CI (with the red X) if the 32-bit windows test fails. This action runner seems extremely flaky, and is currently broken, and I am worried that the red X loses its significance to us if some tests are implicitly expected to fail. (Not to mention it is a visual cue for a package being maintained or not)

I also skip failures on julia-nightly. They are still visible though if you read the logs.

(I remember there was some discussion of whether 32-bit Windows is actually supported or not..... I forget where that was; maybe a PyCall.jl issue? Or in juliaup?)

32-bit Windows is not very high on my priority list, so I agree it can be optional. I would like to know what is causing the error though.

[MilesCranmer]

Yeah I agree we should try to fix it eventually. (But in the meantime it would be nicer to have it just be an optional check)

[MilesCranmer]

I wonder what the other tests keep randomly failing on. Is there any multiprocessing that you know of in the tests? I have had luck preventing segfaults on github actions by specifying a conservative --heap-size-hint. Just seems like the garbage collection needs to be more aggressive on action runners otherwise it gets killed.
